Energy-efficient computing has now become a key challenge not only for data-center operations, but also for many other energy-driven systems, with the focus on reducing of all energy-related costs, and operational expenses, as well as its corresponding and environmental impacts. However, current intelligent data models are typically performance driven. For instance, most data-driven machine-learning approaches are often known to require high computational cost in order to find the global optima. Designing more accurate intelligent data models to satisfy the market needs will hence lead to a higher likelihood of energy waste due to the increased computational cost. This paper thus introduces an energy-efficient framework for large-scale data modeling and classification/prediction. It can achieve a predictive accuracy comparable to or better than the state-of-the-art machine-learning models, while at the same time, maintaining a low computational cost when dealing with large-scale data. The effectiveness of the proposed approaches has been demonstrated by our experiments with two large-scale KDD data sets: Mtv-1 and Mtv-2. [ABSTRACT FROM AUTHOR]
